Suu Kyi faced a maximum sentence of five years in jail.

Myanmar's military regime has been widely condemned for bringing fresh charges against Suu Kyi, who has already spent 14 of the past 20 years in detention.

Yettaw, 53, who swam uninvited to Suu Kyi's home-cum-prison May 3 and stayed there until May 5, provided authorities with a pretext for accusing Suu Kyi of breaking the terms her detention, which officially ended May 27.

Yettaw, a Mormon, was last week hospitalized at Yangon General Hospital with epilepsy. On Monday night he was returned to Insein Prison to face sentencing.

Myanmar authorities have reportedly granted a visa to US Senator Jim Webb, a Democrat of Virginia and chairman of the Subcommittee on East Asia and the Pacific of the Senate Committee on Foreign Relations, to visit Myanmar this week.

Sources in Washington said Webb will ask the regime to release Yettaw on humanitarian grounds.

Suu Kyi's trial prompted widespread criticism by the governments of Western democracies and even Myanmar's close allies in the Association of South-East Asian Nations (ASEAN).

US President Barack Obama has called it a 'show trial', and UN Secretary General Ban Ki-moon, who visited Myanmar last month, has warned that a failure to free Suu Kyi and other political prisoners would undermine the credibility of Myanmar's planned general election in 2010.

But Myanmar's military leaders reportedly fear that a free Suu Kyi could unduly influence the outcome of their planned polls.

Suu Kyi leads the National League for Democracy party that won the last Myanmar election in 1990 by a landslide even though she was under house arrest at the time of the polls. The party has been barred from power ever since.
